The behaviour here is not a bug. The rule that braces fully delimit
the interpolatable expression is a deliberate one, of long standing, and
deliberately different from the syntax of array/hash element references
outside quotes. The treatment of "${^CAPTURE}[0]" is consistent with
that of "${foo}[0]", and for that matter with "${^MATCH}[0]" which can
quite easily be used deliberately. Hat-based variable names have no
less need for this delimitation than other variable names.
If this rule were to be changed, it would require a deprecation cycle.
But we should not change it, and this ticket should be closed.
